To some extent the problem is too much rather than too little imagination. With fiat money, and a discretionary central bank, it’s always theoretically possible to have the money stock (or some other nominal variable) behave just like it ought to, according to whichever macroeconomic theory or model one prefers. In other words, a modern central bank is always technically capable of doing the right thing, just as a chimpanzee jumping on a keyboard is technically capable of typing-out War and Peace.
